Abstract (en)
[origin: EP0055526A2] A hammer control system for a band printer has a micro-processor (12) receiving character information and having an address (ADR) and a data bus (BUS) output together with a timing output. The microprocessor controls an optioning scheme used in the printer. A decoder (16) is connected with the address output of the microprocessor and a print line buffer (20) provides a stored print data output for subsequent comparison and printing connected with said decoder. A compare circuit (22) receives the output of the print line buffer and receives data from the microprocessor. A shift register (28) receives a compare signal from the compare circuit and a shift control signal from the microprocessor. A hammer driver device (30) causes printing to occur in response to the output of the shift register.
